OSHA and the American Society for Testing and Materials (ASTM) agree, and each has set a standard of 0.5 COF or higher for flooring surfaces. However, the Americans with Disabilities Act (ADA) specifies a coefficient of friction of 0.6 on flat surfaces and 0.8 on ramps.
What is a concrete air test?
Concrete entrained air testing is a must for such concrete. Air content of the freshly mixed concrete can be measured by gravimetric, volumetric, or pressure methods. The pressure method is the most commonly used, and in this method a calibrated air meter is used to test a known volume of concrete that is subjected to a defined pressure.
What is air content test?
Air Content Test. An air content test is required for checking air entrained concrete. The method of testing is given in BS EN 12350-7, which replaces BS 1881: Part 106. Method A outlines the principle of the test.
